The “Key” Makes MAT Unique

Each U.S. and Canadian address is assigned a Melissa Address Key (MAK), which is a 10-digit number that never changes. Much like a barcode or ISBN, this address key identifies a discrete physical address and aligns a multitude of additional information associated with the address. When you purchase MAT, you have all of the valid addresses within a given area – and no matter how the addresses change, or if new addresses become available, you know exactly what the changes are.

How to Use MAT

MAT is a boon to the first responder community – imaging a complete database of all residential and business addresses that is up-to-date easily accessible by fire departments or 911 emergency call centers to quickly identify an address and ensure help reaches the correct location immediately.

Additional uses of MAT include optimizing route planning and resource allocation, enriching data for analytics, utilities management (water/gas/waste), and risk assessment.
